## Description

Push your skiing to true elite performance with the Booster Strap World Cup Ski Boot Power Strap by SkiMetrix, the most aggressive and high-response Booster model ever made. Used by Olympic racers, World Cup athletes, and the most demanding freeriders, the World Cup version delivers maximum precision, control, and power transfer for expert-level skiing. Unlike standard ski boot Velcro straps, the Booster WC uses high-strength elastomeric webbing that stretches under load to eliminate dead space between your shin and boot tongue. This creates a secure, locked-in feel while still permitting controlled forward flex, giving skiers explosive rebound, lightning-fast edge engagement, and better stability in variable conditions. The elastic design also acts as a shock absorber, dramatically reducing shin bang and vibration—even during high-speed carving, gate impacts, big-mountain drops, or boilerplate snow. The cam-style buckle provides a precise, secure hold, allowing easy micro-adjustments and consistent power transmission all day long. The Booster Strap WC integrates seamlessly with ski straps, ski carriers, boot gloves, neoprene boot covers, ski boot stretchers, and other ski-boot accessories. Whether you're running race gates, hammering steep lines, or simply demanding maximum performance from your gear, the SkiMetrix Booster Strap World Cup is the ultimate power strap replacement—delivering unmatched stiffness, control, and confidence for expert skiers who refuse compromise.

Review: Turn your boot game up a notch - As an expert-level skier logging 100+ days on snow each season, the Booster Strap for Ski Boot by SkiMetrix World Cup has legitimately changed my boot game. The construction feels rock solid — no flimsy nylon — and it cinches down smoothly so I can fine-tune the tension exactly how I want it. On long charging days, I can tighten up for locked-in edge control, and on softer snow I back it off without fuss. It noticeably reduces heel lift and gives a more direct feel through every turn. I ski a mix of big mountain, ice, and crud, and this strap has held up under all of it with zero loosening or wear. Simple install, no weird quirks, and it actually makes my boots perform closer to how I want them to. If you’re pushing hard every day and want that extra connection to the snow, this is worth every penny.
Review: Great Product - notice the strap level “World Cup” - Hi everyone, This is a great product to incorporate into your boot system. Just know, there are levels of strap tension. For example “World Cup” is synonymous with a very rigid strap for limited flex. This is what I purchased not knowing there were different levels, I just knew the name “booster” but not the level, example “World Cup”, “Expert” and “Intermediate”. Now I know - duh. All I know is that I purchased the “World Cup” but a great technician (Sam) at Surefoot in Park City, showed me how to relieve the tension of the strap by cutting an internal band. ATTENTION: don’t do this unless you know exactly what to do! Otherwise, you’ll ruin the strap. The theory of the strap is like a thick rubber band that creates more tension as it is expanded and less when relaxed but there is some amount of tension. Unlike the typical strap that comes on most boots that when you crunch or push your shins into the tongue of the boot, you engage pressure through the boot in to the skis. But the typical strap is on/off and once you disengage the shin from the boot tongue, there is no pressure. The booster strap changes that paradigm by increasing/decreasing the amount of pressure to the boot tongue in increments, not on/off. I hope this helps

### ⭐⭐⭐⭐⭐ Big improvement over OEM straps
*by R***T on December 27, 2025*

Booster straps are great. Much better than the Velcro straps that come with my original lange boots. These don’t slip and ice doesn’t get in them.
